Abstract

This paper introduces the Multiple Input Multiple Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM) and Low Density Parity Check Code (LDPC). Then, this paper gives the improved log domain Back Propagation (BP) decoding algorithm optimizing the variable nodes and simplifying the check nodes. The ameliorate approach can reduce the decoding complexity, at the same time improving the decoding performance. Finally, builds a MIMO-OFDM communication system. Then it studies the application of LDPC on the MIMO-OFDM systems. Taking use the software simulation, this paper compares the influence of Bit Error Rate (BER) performance of different parameters on the system.
